I asked the owner of Arboretum Skin Care, Olga, what types of ingredients we should avoid using on young children. While she only creates skin care solutions and remedies for adults, she is both my aunt and a molecular biologist, so I value her opinion! She said that babies and kids should avoid ingredients such as PABA, sodium lauryl sulfate, mineral oil, lanolin, perfumes, pigments and dyes.  She added that preservatives such as formaldehyde, parabens and diazolidinyl urea should be avoided as well.  She explained that all of these ingredients can cause allergies and contact dermatitis. She also said that most of the time petroleum jelly (Vaseline) is pretty harmless, but that it can clog pores. ~ Parents: Have you found any baby bath or skin care products that you especially like? ~
